Why does the cdm probe of a robot in maintenance mode generate a BootAlarm when the robot is restarted?

Answer:

The maintenance mode suppress all alarms greater that Information. The reason why the alarm is generated is, by default, the BootAlarm severity is set to Information. Changing the Severity to any other level will prevent the alarm to be generated: open the cdm GUI > Setup tab > Message definitions > double click BootAlarm > change the Severity > OK > Apply > OK.
